TANK-SIPHON FOR LOCOMOTIVES.

Specification of Letters Patent.

Patented May 6, 1913.

I Application filed September 3, 1912. Serial No. 718,261.

To all whom; it may concern:

Be it known that I, JAMES E. MURRAY, a citizen of the United States, residing at Albuquerque, county of Bernalillo, and State of New Mexico, have invented certain new and useful Improvements in Tank- Siphons Vfor Locomotives, of which the following is a specification. Y

My 'nvention relates to tank siphons for locomotives; and theobject of my invention is to provide an improved siphon of the class mentioned equipped with means for cleaning the feed water as it passes from the tank to the injector. In most devices of this character. as heretofore provided, the filter or cleaning device 'is so arranged that it is inaccessible for cleaning while the locomotive is inaction orwhile the tank contains much water; and in those wherein the filtermay be cleaned while the locomotive is running or while the-tank is filled, the larger portions or particles of foreign matter are thrown'back into the tank whence they again pass to and clog the filter or the siphon.

A further and particular object of my invention is to provide a device of the class mentioned which shall remove suspended matter from the feed water as it passes to the injector and prevent the larger particles from returning to the tank. and of such construction that the filtering device shall be accessible at.all times for cleaning and removing the accumulated matter.

Other objects will appear hereinafter.

\Vith these objects in view my invention consists in arranging the siphon with its upper end projecting through and above the top of the tank, forming the siphon with a strainer box at its upper end provided with a removable closure and arranging a strainer within the strainer box, the strainer being constructed to receive .and hold the matter separated from the water.

My invention further consists in a device as mentioned in which the strainer may be readily removed.-

My invention further consists in providing the bottom of the tank with a depression or well and extending the mouth of the siphon into the well in order that all 'of the water in the tank may be withdrawn through the siphon.

My invention further consists in various details of construction and arrangements of i a flange base 9, an

closure 14.

parts all as will be fully described hereinafter and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this s iecification and in which- Figure l is a vertical section of a device embodying my invention, Fig. 2 is a plan v ew of the same with the closure of the strainer box removed and a portion of the top Wall of the strainer broken away, and Fig. 3 is a. vertical section through the strainer taken on the line az-w of Fig. 2.

Referring now to the drawings 1 and 2 indicate the plates forming the top and bottom walls respectively of the water tank of a locomotive. The bottom 2 is preferably provided with an aperture 3, and secured to said bottom beneath said aperture is a concave member 4 forming a well 5. Secured to the member 4 is a pipe connection or goose neck 6 leading to the injector. Threaded into the upper end of the COL 'c' tion 6 is a vertically disposed pipe 7 whlch extends upwardly above the top plate 1.

Arranged above and secured to the top plate 1 is astrainer box 8. This comprises upwardly flared conical body portion 10 preferably terminating in a cylindrical upperpcrtio n 11, and a top 12, the latter being provided with an enlarged aperture 13 into which is threaded a. cap or 15 indicates a ventarranged in the side of the box 8. j Threaded into the lower 'end or base of the strainer box '8 is :1 depending pipe 16 which extends downwardly into the well and contains or surrounds the pipe 7. In the event that a. horizontal partition 17 is provided in the tender" dividing a lower watertank 18 from the upper 'air space 19. a. stutiing box 20 is provided on the partition 17 surrounding the pipe 16 to prevent the water from the tank entering the space 19. Arranged upon the upper end of the pipe 7 and within the box 8 isthe strainer. This comprises [an upwardly flared body portion 21, a foraminated plate 22 arranged therein, and a cage :23 projecting above the upper edge thereof. The plate 22 is concave and is preferably formed of perforated sheet metal. The cage 23 is formed with a frame comprising a plurality of vertical members 24, the lower ends of which are secured to the body member 21, and a ring secured to the upper ends of the members 24. The sides and top of the frame thus formed are covered with wire mesh 26 and inwardly swinging doors 27 are provided upon opposite sides between adjacent members 24. The cage is preferably formed with flat parallel sides as shown in Fig. 2 and the doors 27 are preferably arranged upon ,the flat sides. vThe doors 27 admit refuse or large particles of foreignmatter drawn up through the pipe 16 and prevent the same from returning to the tank. Should suflicient matter accumulate in the cage to prevent free operation of the siphon the strainer may be readily lifted from the box 8, after the clo-' sure 14 is removed, and quickly cleaned and replaced. It is obvious that on account of the arrangement of the box 8, the cleaning may be accomplished at any time, irrespective of the depth of water in the tank and whether the locomotive is runnin or not.

To "prevent vibration of the pipes 7 and 16, set screws28 and 29 are provided. The

screws 28 are threaded through the pipe 7 filtering the water and entrappingthe matter filtered therefrom.

2. A locomotive water tank in combina tion with a siphon comprising a strainer box fixed to and projecting above the top of said tank, a pipe depending from. said box, a pipe connection at the bottom or? said tank, a vertically disposed pipe fixed to said connection and extending upwardly through the first said pipe into said box, means on the upper end of said last mentioned pipe and within said box for filtering the water and entrapping the matter filtered therefrom. r

3. A locomotive water tank in crimbina tion with a siphon comprising a strainer box sure for said opening accessible from the top of 831d tank, a pipe depending from said box, a pipe connection at the bottom of said)? tank, a vertically disposed pipefixed tosaid connection and extending upwardly to the first said pipe into said box, andmeans on the upper end of the last mentioned pipe and within said box for filtering the water.

4. A tank, in combination with a siphon and means in said siphon for filtering the provided with an opening in its top, a clowater and entrapping the matter filtered therefrom, said means comprisin a body. portion, a screen in said body portion, a IO.-

raminated cage covering the upper end of said body portion and an inwardly swinging gate in said cage.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
